Short Communication

Chrononutrition is a field of Chronobiology that establishes the principle of consuming foodstuffs at times of the day when they are more useful for health, improving, therefore, biological rhythms and physical performance [1]. Every trial carried out by our research group in this field has shown that some nutrients may influence some circadian functions, but they may also be positive for health in ageing and some neurological disorders [2].

But not only ageing or neurological diseases make us suffer from chronodisruption. In fact, mainly, there are two causes of chronodisruption, they are chronic changes in timing of light and behavioral activity (physical activity, rotating shift work, meal times, etc.) [3]. When the sleep/wake circadian rhythm shows chronodisruption symptoms and becomes uncoupled with the endogenous timing system, normal day/night variations in many hormones and neurotransmitters are altered and may have adverse health consequences [4]. Our research group, in this communication, aims to provide some nutritional tables to be taken into account for mood disorders due to the strong and growing community interest in the effects of nutrition and dietary factors on mental health.

Triptophan-enriched diets may achieve beneficial effects on serotonin or melatonin levels with their consequent positive influence on health [5]. In this way, our research group has searched scientific databases to elaborate tables of foods whose composition shows high levels of tryptophan, serotonin, or melatonin. To carry out this objective we looked for tryptophan content food in USDA database, related to indoleamines riched food we used the descriptors “serotonin” and “melatonin” in PubMed, Science Direct and Google Scholar scientific databases.

We recommend tables showed in this letter for the design of diets to improve sleep disorders, those neurological diseases related with impairments in indolamine levels, or psychological disorders like anxiety or depression.

Moreover, to design a triptophan-enriched diet it is important to take into account that meals must have at least some glycaemic effect in the blood. Tryptophan ingested with glucides is better transported into the blood. This is provoked by insulin secretion which induces the entry of Large Neutral Amino Acids (LNAA: leucine, isoleucine, tyrosine, phenylalaline and valine) into muscle cells [6]. This fact is particularly relevant due to tryptophan being transported bound to albumin, such as LNAA; in this way a glycaemic meal with high levels of tryptophan should be better at increasing serotonin and melatonin levels in blood (Tables 1-3).
